In　the　field　of　automotive　lightweight　manufacturing,　the　advanced　high-strength　steel　(AHSS)　sheet　gets　a　pivotal　position　owing　to　a　good　match　between　the　plasticity　and　superior　strength.　However,　in　the　complex　multi-step　loadings,　the　twist　springback　phenomenon　generated　by　irregular　and　curved　stampings　has　arisen　great　concerns.　In　this　article,　the　material　DP500　is　adopted　for　the　twist　springback　analysis　in　a　two-step　loading　experiment.　First,　the　large　bone-shaped　specimen　is　deformed　to　4%　strain　along　the　rolling　direction.　Subsequently,　the　forming　blank,　cut　from　the　large　specimen　at　different　directions,　is　stamped　in　a　die　to　form　a　3D　curved　channel.　Meanwhile,　the　simulation　analysis　of　the　two-step　loading　procedure　is　built　for　twist　springback　prediction.　An　advanced　distortional　hardening　model　incorporated　with　an　attenuated　modulus　model　is　applied　for　exactly　capturing　the　deformation　features　under　mutative　strain　path.　A　deep　analysis　with　regard　to　the　residual　stress　and　elastic　modulus　distribution　is　conducted　to　evaluate　the　pre-strain＇s　influence　on　the　twist　springback　of　this　curved　part.　The　result　shows　that　mutative　strain　path　induced　by　the　change　of　the　pre-strain　axis　has　a　significant　impact　on　the　twist　springback.　©　2020　The　Authors
